be applied to a viewport.</p>
<p>QWebPage.ViewportAttributes provides a description of a
viewport, such as viewport geometry, initial scale factor with
limits, plus information about whether a user should be able to
scale the contents in the viewport or not, ie. by zooming.</p>
<p>ViewportAttributes can be set by a web author using the viewport
meta tag extension, documented at <a href="http://developer.apple.com/safari/library/documentation/appleapplications/reference/safariwebcontent/usingtheviewport/usingtheviewport.html">
Safari Reference Library: Using the Viewport Meta Tag</a>.</p>
<p>All values might not be set, as such when dealing with the
hints, the developer needs to check whether the values are valid.
Negative values denote an invalid qreal value.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="ViewportAttributes" />ViewportAttributes.__init__ (<i>self</i>)</h3><p>Constructs an empty <a href="qwebpage-viewportattributes.html">QWebPage.ViewportAttributes</a>.</p>


<h3 class="fn"><a name="ViewportAttributes-2" />ViewportAttributes.__init__ (<i>self</i>, <a href="qwebpage-viewportattributes.html">ViewportAttributes</a>&#160;<i>other</i>)</h3><p>Constructs a <a href="qwebpage-viewportattributes.html">QWebPage.ViewportAttributes</a>
which is a copy from <i>other</i> .</p>


<h3 class="fn"><a name="devicePixelRatio" />float ViewportAttributes.devicePixelRatio (<i>self</i>)</h3><h3 class="fn"><a name="initialScaleFactor" />float ViewportAttributes.initialScaleFactor (<i>self</i>)</h3><p>Returns the initial scale of the viewport as a multiplier.</p>


<h3 class="fn"><a name="isUserScalable" />bool ViewportAttributes.isUserScalable (<i>self</i>)</h3><p>Determines whether or not the scale can be modified by the
user.</p>


<h3 class="fn"><a name="isValid" />bool ViewportAttributes.isValid (<i>self</i>)</h3><p>Returns whether this is a valid <a href="qwebpage-viewportattributes.html">ViewportAttributes</a> or
not.</p>
<p>An invalid <a href="qwebpage-viewportattributes.html">ViewportAttributes</a> will have
an empty <a href="qsize.html">QSize</a>, negative values for scale
factors and true for the boolean isUserScalable.</p>


<h3 class="fn"><a name="maximumScaleFactor" />float ViewportAttributes.maximumScaleFactor (<i>self</i>)</h3><p>Returns the maximum scale value of the viewport as a
multiplier.</p>


<h3 class="fn"><a name="minimumScaleFactor" />float ViewportAttributes.minimumScaleFactor (<i>self</i>)</h3><p>Returns the minimum scale value of the viewport as a
multiplier.</p>


<h3 class="fn"><a name="size" /><a href="qsize.html">QSize</a> ViewportAttributes.size (<i>self</i>)</h3><p>Returns the size of the viewport.</p>
